Did anyone who retrofit the M-sport bumper have problem installing the air duct beside the lower mid grille? The shop i went to said that the bracket for the air ducts didn't match so they have to drill the chassy. I definitely dont want to drill the chassy. Anyone?

Been trying to help you on this via email as you said your installer cannot figure it out. No new holes should be drilled at all. Maybe email me some pics of where they are wanting to drill and we can help further. Thanks

According to this photo there are Deformation elements that need to be replaced, also probably the "mount, bumper, front,lower" (position4) also needs to change. I have a sport line that I am putting this bumper on and it's not that easy swapping, my ducts do not align too well with the supposed holes where they should be mounted on.

Also, what about the shroud for,the radiator in the right wheel well? If you have pictures of all the ducts on the car with the bumper off, it would be very helpful.

That is a pretty nice deal, but you will need more than just the bumper cover, meshes and brake ducts.
You also need central duct, both sides deformation elements and the cross member that goes between them, new shock absorber element, wheel housing front cover deflector elements on both sides, and potentially new shrouds for your auxiliary radiators.

I looked through this thread and couldn't find any pictures. Does anyone have pictures of sport line with m sport front bumper only. I want to see what retrofitting the front bumper would look like without doing the rest.

How much did the retro fit bumper cost and the cost of installation and paint?
Thanks

Mine is not a retrofit. This is a $600 OEM bumper. Additionally, to have it done right you will need everything that is laid out in post #2 from ModBargins (http://www.f30driver.com/forum/showthread.php?t=1011959), plus a lower cross bar that is bolted to those aluminum crash elements upfront, which is not pictured ($80 from a dealer).

Also note that there are 2 dampers for curb descent (#6 on this diagram) that attach to these aluminum deformation plates (#5), via a 1/4" blind rivet (#14), which you will need to install with a pneumatic gun.

Those same deformation elements also have auxiliary radiator brackets that attach to them through a rivet, so it's not quite an easy-breasy job for a guy without correct tools. Don't get me wrong, I will probably add ModBargin rear bumper and sides next year, I just don't want you think that you can order theirs shipped to a body shop and they will have everything you need. They'll need to buy a couple smaller items, which are not that big of a deal.

I did the installation myself and had a family friend who works at a body shop do the paint, so those costs would not be meaninful to anybody on this forum.

I wouldn't buy from mod bargains though, the same exact m retrofit can be purchase from ebay. Also, the pics aren't his. Here is the original tread where MB used the same exact pics. http://www.f30post.com/forums/showthread.php?t=851670
